Hi a newbie here. Acer 2010 with 2 x 512mb, will not start, gets continuous beep during POST and no further. Fan runs for a moment, no screen display, LED light remain on. Tried to swap the two memory slots, tried with one mem card, same problem. Tried both ac power and battery, same results. Could it be both mem cards are faulty, or perhaps p/supply problem in the MOBO. Any suggestions appreciated.
